    Flange For Alphax #3?

    Hello All,

    I am trying to find a flange or retaining ring to fit an Alphax #3 shutter. The thread specs are: 3.117 inch diameter and 30TPI. I am looking for a lower priced alternative to units available from Grimes and e-bay (fall-back plans B & C).

    I am willing to re-purpose something in the short run.

    There are only three types of mounting flanges; too big, too small and wrong thread!

    Typo alert: The shutter is an Alphax #5. The Thread dimensions are as posted above 3.117"/ 30 TPI.

    You may have to do what I did, I took some 1/8 birch plywood and made my own lens board and made the hole a touch
    under size so I could screw the lens in to the wood since wood will not damage the threads :
